From a shooting standpoint, we all have heard the term "punch" referring to a caliber's ability to knock an animal off it's feet - rendering it helpless. As a general question, and the reason why it's being asked, I understand the 45-70 due to it's lower velocities, doe's not produce enough energy to create a punch factor to shock an animal's nervous system. A factor critical for a centerfire cartridge.
I realize a 45-70 will never produce the same hitting results as a .340 Weathery, for comparison sake. But, as a member of this forum, I have read numerous articles on the cartridge but never received the feeling that it's enough for dangerous game. Any input, would be appreciated.
